.Laim Patent No. 94,821, dated satana 14, 1869.

To all whom 'it may concern Be it known that I, J osErH HATHAWAY, ofWoodstock, in the county of Windsor, and State of Vermont, have inventeda new and useful Improvement in Water-Wheels; and I do hereby declarethat the following is a full, clear, and exact description thereof,which will enable others skilled in the art/to make and use the same,reference' being had to the accompanying drawings, forming part of thisspecification- This invention relates to new and useful improvements inwater-wheels, whereby many of the objection'sto the ordinary arrangementot' the chutes and 'parts connected therewith areobviated; andcousistsin the method of hanging, adjusting, and operating the chutes, and inthe form of the buckets of the wheel, and their arrangement in regard tothe chutes, as will behereiafter more fully described.

In the accompanying plate of drawings- Figure 1 is a vertical section ofthe wheel through the 1line :c :v of iig. 2.

Figure 2 is a top view, with a portion of the top plate broken away, toshow the levers for operating thel chutes.

Figure 3 is a horizontal section of fig. l, through the line y y.

Similar letters of reference indicate corresponding parts. A representsthe wheel, which is attached to a vertical shaft, B, and confined in theordinary casing, which consists of a lower flanged cylinder, C, which is'placed tlnough the floor, as represented in iig. 1,

and an upper plate, D. The plate and the cylinder are connected togetherby bolts or screws.

E represents the chutes.

The chutes are in width suicient to fill the sp/ace between the plate Dand the flange F F of the cylinder, and still be allowed to move freelyfor enlarging, diminishing, or closing up entirely thedischargeorifices.

These chutes are pivoted near their inner ends, as seen at g. Theirother ends are left free.

h represents posts, whose lower ends are placed in orifices in theflange F' of the cylinder C. They pass up` through the plate D, to theupper ends of which the levers I are attached, as seen in tig. 2.

Between the flange F' and the plate D, these posts are cams, as seen intig. 3.

It will be seen that when the cams are turned by the 4levers against thechutes, the water-spaces J will be increased in area, and when the camsare turned in the other direction, the pressure of the water upon theirouter sides will close them up, as seen in the drawing in red color.

K is a plate, which is passed down overtheueckL of the plate D,'tl1ecollar of which rests on D, as seen in iig. 1.

m represents rolls, which are attached to the under side ofthe plate Kby pivots'. These rolls occupy the spaces between the levers I, so thatwhen the plate K is moved, or partially revolved, the levers will bemoved, which will cause the cams toact against the chutes, to throw'them out against the pressure of the water and open the water-spaces.

The plate K is partially rotated by means of the rackN (which is fast toit) and the pinion O on the' vertical shaft P.

A crank or Inruil-wheel is fitted to the top of' the shaft P, by whichthe rack and pinion are opeiatedlv:

The plate K is kept down and in place by means of the screws T, whichenter the plate beneath and stand,b in slots a in the plate. The headson the screws prevent tbe plate from raising, tyhile the lengt-h of theslots fu, limit the extent of its movement.

R represents the buckets of the water-wheel. The water acts mainlyagainst the lips S of the buckets. 'lhe power is applied, it will beseen, where it will produce the greatest effect.

By this arrangement, the quantity of water used ou the wheel may beregulated with the greatest nicety, while the amount of power requiredfor adjusting the chutes is very slight, in consequence of the powergained by the rack and pinion,and the absence of friction in moving thelevers I.

Having thus described my invention,

What I claim as new, and desire to secur'e by Letters Patent, is'- 1.'lhe chutes E and-cam posts h, constructed, arranged, aud operatingsubstantially as and for the purposes shown and described.

2. The levers I, and the plate K, with the rolls m,

combined, arranged, and operating'substantiall y as described, for thepurposes set forth.

3. In combination with the chutes E, arranged and operating asdescribed, the lips S on the buckets R, substantially as and for thepurposes set forth.

The above specification of my invention signed. by'

me, this 22d day ot'V April, 1869.
